E-Selectin ELISA Kit (CD62E)

INTENDED USE

Human E-selectin ELISA kit is designed for detecting in vitro quantitative levels of e-selectin (ELAM-1, CD62E, LECAM2) in human serum, tissue homogenates, plasma and other biological fluids. This assay has a minimum sensitivity limit of 46.875 pg/ml.

BACKGROUND

E-selectin (also called LECAM2, ELAM-1 and CD62E) is only expressed in endothelial cells that have activated by cytokines and it is a cell adhesion molecules which consists of 6 sushi domain units, EDF-like domain, transmembrane domain, intracellular cytoplasmic tail, C-type lectin domain and an N-terminal.

Like many of the other selectins, E-selectin is also responsible in playing vital roles during inflammation – it is important in recruiting leukocytes to the site of injury. Cytokine activated endothelial cells that are expressing it have the ability to bind CD44, PSGL-1 and many other ligands which are unidentified.
